I am certain it’s been answered somewhere, but a search of Yahoo, Ask Jeeves and the SDMB have yielded no answer. I did a search of “The Straight Dope” and found that uncle Cecil explained Margaret to Peggy, but a conversation in the office has gone to numerous names (beyond Margaret/Peggy) and their derivatives—nicknames. To further eradicate ignorance wherever it lurks, I pose the question to the TM: How are nicknames derived? And in particular, these nicknames…
Richard – Dick?
Charles – Chuck?
Robert – Bob?
I think there were more but I’ll have to check back with the sales team who are chattering on about them. (Incidentally I couldn’t find the answers at behindthename.com, a name etymology website.)
(This is my first ever GENERAL QUESTION—Woohoo!)
